Classification of Electromagnetic Stirrer for Bloom (Round)
There are three kinds of EMS according to installation position:
1. Mould Electromagnetic Stirrer : M-EMS
2. Strand Electromagnetic Stirrer: S-EMS
3. Final Electromagnetic Stirrer: F-EMS
So far, most of steel plant use M-EMS or M+F-EMS.
Features of Electromagnetic Stirrer for Billet (Round)
Mould EMS (M-EMS)
EMS inside mould using mould water: EMS is installed inside the mould and uses cooling water system of the mould. It can be operated conveniently with low cost. Stirring freq: 2 ~ 8Hz. (Refer to Fig.1)EMS inside mould using clean water: EMS is installed inside water jacket of the mould and uses a separate cooling water system. Structure is compact and life is long. Stirring freq: 2 ~ 8Hz. (Refer to Fig.2)EMS outside mould: EMS is installed outside the mould with separate cooling water system. It is simple to change copper tube. EMS can be used for wide range of sections. Stirring freq: 2 ~ 5Hz. (Refer to Fig.3)Inner cooling type ems:can be installed inside or out the mould.cramer windings are adopted,which has even magnetic field without polarization.But magnetic leakage is too much with electromagnetic pollution cooling water quality has to be very strict and operation cost is higher.Stirring freq is 1~ 6Hz. (Refer to Fig.4)
